I wouldn't do much different. Rockchucker combo kit treated me well.
As far os the shotgun reloading, I would like to sell that Dillon SL900 12-gauge system I have. I don't use that nearly as much as I thought I would. Traded a guy a Knight UL ML for it. Wish I had kept the ML at this point.
I would have skipped a single stage press and got a turret instead. I took out the auto indexer and mostly use my turret like a single stage anyway, but I like having each set of dies on its own swappable plate, all set to the proper depth and ready to go. Even though I have a progressive press now, the turret still gets the most usage by far.
With components at ridiculous prices and no hope for the future, I typically don't recommend folks getting into reloading. I'm glad I stockpiled everything years ago, when we reloaded because it saved money and allowed us to produce more accurate loads than factory. Neither holds as much truth today.
Goodby Rockchucker press. It was gifted down the totem pole.
Hello Rebel press. It’s just slightly beefier (22%) than the Rockchucker, otherwise essentially a close relative. Now, I’ve never known anyone who has broke a Rockchucker forming cases let alone simple full length resizing, but I like bigger. Lol
So, to answer the original question, I’d get a RCBS Rebel kit, not the Rockchucker kit. Lol
